ObjectiveTo systematically review the correlation between the birth number and the risk of breast cancer of Chinese female. MethodsWe electronically searched databases including the CNKI, WanFang Data and VIP databases from inception to September 1st 2015, to collect case-control studies about the correlation between the number of births and the risk of breast cancer among Chinese female. Two reviewers independently screened literature, extracted data, and evaluated the risk of bias of included studies. Then meta-analysis was performed by using Stata software. ResultsA total of 14 case-control studies involving 3 428 patients and 3 906 controls were included. The results of meta-analysis showed that:the females who had term birth had significant lower incidence of breast cancer than those without childbirth history (OR=0.429, 95%CI 0.322 to 0.571). Subgroup analysis based on the number of term birth showed that:Compared with the female without childbirth history, those who had term birth of one time (OR=0.464, 95%CI 0.321 to 0.670), two times (OR=0.394, 95%CI 0.269 to 0.576) and≥3 times (OR=0.340, 95%CI 0.232 to 0.499) had significant lower incidence of breast cancer. ConclusionTerm birth is a protective factor for breast cancer of Chinese female, and more times of term birth will decrease the risk of breast cancer.
ObjectiveTo systematically review the efficacy of interactive message management on patients with type 2 diabetes mellitus (T2DM).MethodsCNKI, VIP, WanFang Data, Web of Science, PubMed and The Cochrane Library databases were electronically searched to collect randomized controlled trials (RCTs) of T2DM with interactive message intervention from inception to May 2021. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed by using Revman5.3 software.ResultsA total of 17 RCTs involving 1 827 patients were included. Results of meta-analyses showed that compared with routine management, interactive message combined with routine management was associated with improvement of glycosylated hemoglobin, fasting blood glucose, body mass index, systolic blood pressure, and total cholesterol in T2DM patients. However, diastolic blood pressure, triglyceride, low-density lipoprotein, or high-density lipoprotein were not improved. ConclusionsThe current evidence shows that interactive message combined with routine management can significantly reduce blood glucose level, body mass index, systolic blood pressure and total cholesterol in T2DM patients. Due to the limited quality and quantity of the included studies, more high-quality studies are needed to verify the above conclusions.
Giant thoracic tumor is currently one of the diagnostic and therapeutic challenges of thoracic surgery, with no established guideline or standard for diagnosis and treatment. The quality control of individualized surgical strategy and perioperative management with multi-disciplinary participation is the key to ensure the safety and improve the prognosis of patients. Based on the clinical experience of our institution and others, we hereby discussed and summarized the basic principles, surgical strategies and perioperative management of giant thoracic tumor, aiming to provide a reference of quality control.
Objective To assess the efficacy and safety of acupuncture versus western medicine in the treatment of depression neurosis. Methods Randomized controlled trials (RCTs) involving acupuncture versus western medicine in the treatment of depression neurosis were identified from CBM (1978 to 2009),VIP (1989 to 2009),WANFANG Database (1998 to 2009), CNKI (1979 to 2009), PubMed (1966 to 2009), EMbase (1980 to 2009), and The Cochrane Library (Issue 4,2008). We also hand searched relevant journals from Tianjin University of Traditional Chinese Medicine. Data were extracted and evaluated by two reviewers independently with a specially designed extraction form. The Cochrane Collaboration’s RevMan 5.0.2 software was used for data analyses. Results A total of 9 trials involving 903 patients were included. Meta-analyses showed that the total effective rate in the acupuncture group was similar when compared with Dailixin (RR= 1.01, 95%CI 0.82 to 1.23) on 20 d, fluoxetine (RR= 1.06, 95%CI 0.82 to 1.37) at week 8, but showing difference between acupuncture and fluoxetine (RR= 1.15, 95CI 1.07 to 1.22) at week 12. As for the HAMD score, no significant difference was noted between acupuncture and Dailixin (WMD= 0.45, 95%CI – 2.47 to 3.37) at 20 d, or amitriptyline at week 6, or fluoxetine on 30 d, and weeks 4, 8, 12; there was a difference between acupuncture and amitriptyline observed at week 1 (WMD= – 2.67, 95%CI – 4.38 to – 0.96) and week 2 (WMD= – 2.18, 95%CI – 3.28 to – 1.08). In terms of the SDS scores, significant difference was found between acupuncture and fluoxetine (WMD= – 4.26, 95%CI – 6.67 to – 1.85) at week 6, but no difference at week 4 and 12. Four trials reported adverse events. One trial found that no adverse events existed in acupuncture according with TESS score, contrasting with thirst, constipation, vision vague, shimmy, fast heart rate, and some change in liver function and cardiogram in amitriptyline group.Two trials reported very low score in acupuncture showing difference when compared with the drugs. And one trial described that four people had stomach and intestinal tract disorders. While no adverse reactions happened in the acupuncture group. Conclusion Acupuncture is not inferior to western medicine, and it is worth noting that acupuncture is associated with few adverse reactions. Further large-scale trials are required to define the role of acupuncture in the treatment of depression neurosis.
Objective To evaluate the efficacy of posterior approach discectomy with and without fusion in the treatment of lumbar disc herniation. Methods We searched MEDLINE (1950 to June 2007), OVID (1950 to April 2007), PUBMED, the China Biological Medicine Database (1978 to June 2007) and Wanfang Database (1981 to February 2007). We also handsearched several relevant journals for randomized controlled trials (RCTs) and quasi-randomized controlled trials (quasi-RCTs) comparing posterior approach discectomy with and without fusion in the treatment of lumbar disc herniation. The quality of the included trials was assessed. The Cochrane Collaboration’s RevMan 4.2.8 software was used for statistical analysis. Results Nine eligible trials involving 1911 patients were included. The meta-analyses found no statistically significant differences between the two operative procedures in the incidence of postoperative leg pain [RR 0.94, 95%CI (0.69, 1.28)], the proportion of patients requiring re-operation [RR 0.77, 95% CI (0.57, 1.04)], the incidence of post-operative lumbar canal stenosis [RR 1.23, 95%CI (0.26, 5.86)], and the relapse rate at other intervertebral spaces [RR 1.05, 95%CI (0.49, 2.26)] (Pgt;0.05).There is statistically significant differences between the two group in the incidence of peri-operative complications [RR 1.46, 95%CI (1.06, 2.00)]. Discectomy plus fusion was superior to discectomy alone in incidence of postoperative back pain [RR 0.70, 95%CI (0.53, 0.94)], relapse rate at either intervertebral space [RR 0.30, 95%CI (0.18, 0.48)] and at the same intervertebral space [RR 0.12, 95%CI (0.04, 0.37)]. Conclusions Since all the included studies were controlled trials with a great potential for biases, high-quality, large-scale randomized controlled trials are required.
Objective To appraise the current situation of randomized controlled trials (RCTs) on information of common-used digestive-related medicines afforded by medicine-salesmen. Methods RCTs on digestive-related medicines were assessed according to clinical epidemiologic standard. Results 60 medicines containing 252 therapeutic articles were searched and 75 RCTs were identified and assessed. Conclusion The qualities and quantities of RCTs of information on digestive-related medicines were of large difference, the RCTs afforded by the joint pharmaceutical enterprises are much better than those of foreign ones and domestic ones.
ObjectiveTo discuss the clinical effects of intercostals nerve freezing technique for analgesia on post-operative chest. MethodsWe included 80 patients with thoracotomy in Zhongshan Hospital in Xiamen University between June 2013 and June 2014. The patients were divided into a trial group (30 males and 10 females at average age of 59.90± 10.62 years) and a control groups (28 males and 12 females at average age of 59.85± 10.52 years) by random digital table. The patients in the trial group were treated with frozen the intercostals nerve roots located in the incision and next intercostals before closing the chest by cryotherapy therapy apparatus (K520 type, Beijing Kulan Company). The patients in the control group were treated with self-control intravenous analgesia pump post-operation. We compared the postoperative incision pain and cough, sputum reflection score, and pulmonary complications between the two groups. ResultsThe pain degree in the trial group was significantly weaker than that in the control group on the first day, the second day and the seventh day after operation (t=-6.45, -4.95, -3.14, P < 0.05). Cough, sputum reflection score were significantly higher than those in the control group (P < 0.01). Pulmonary complications were significantly lower (t=3.023, P < 0.05). There were 4 patients with pneumonia and no pulmonary atelectasis in the trial group. While there were 8 patients with pneumonia in the control group and 1 patient with pulmonary atelectasis. ConclusionIntercostals nerve freezing technique can drastically reduce postoperative pain in the patients with open thoracic operation, effectively promote patient cough and expectoration, and reduce pulmonary complications rate.
ObjectiveTo explore the effect of different ventilation modes on pulmonary complications (PCs) after laparoscopic weight loss surgery in obese patients. MethodsThe obese patients who underwent laparoscopic weight loss surgery in the Xiaolan People’s Hospital of Zhongshan from January 2019 to June 2023 were retrospectively collected, then were assigned into pressure-controlled ventilation-volume guaranteed (PCV-VG) group and volume controlled ventilation (VCV) group according to the different ventilation modes during anesthesia. The clinicopathologic data of the patients between the PCV-VG group and VCV group were compared. The occurrence of postoperative PCs was understood and the risk factors affecting the postoperative PCs for the obese patients underwent laparoscopic weight loss surgery were analyzed by multivariate logistic regression analysis. ResultsA total of 294 obese patients who underwent laparoscopic weight loss surgery were enrolled, with 138 males and 156 females; Body mass index (BMI) was 30–55 kg/m2, (42.40±4.87) kg/m2. The postoperative PCs occurred in 63 cases (21.4%). There were 160 cases in the PCV-VG group and 134 cases in the VCV group. The anesthesia time, tidal volume at 5 min after tracheal intubation, peak inspiratory pressure and driving pressure at 5 min after tracheal intubation, 60 min after establishing pneumoperitoneum, and the end of surgery, as well as incidence of postoperative PCs in the PCV-VG group were all less or lower than those in the VCV group (P<0.05). The indicators with statistical significance by univariate analysis in combination with significant clinical indicators were enrolled in the multivariate logistic regression model, such as the smoking history, American Society of Anesthesiologists classification, hypertension, BMI, operation time, forced expiratory volume in 1 second (FEV1), FEV1/forced vital capacity, and intraoperative ventilation mode. It was found that the factors had no collinearity (tolerance>0.1, and variance inflation factor<10). The results of the multivariate logistic regression analysis showed that the patients with higher BMI and intraoperative VCV mode increased the probability of postoperative PCs (P<0.05). ConclusionsFrom the preliminary results of this study, for the obese patients underwent laparoscopic weight loss surgery, the choice of ventilation mode is closely related to the risk of developing postoperative PCs. In clinical practice, it is particularly important to pay attention to the risk of postoperative PCs for the patients with higher degree obesity.
The existing mazes are mainly used to study the learning and memory of animals. However, there is still a lack of corresponding maze and method in the aspect of the observation and test of aquatic animal robots. For this purpose, the authors have developed a three-dimensional water maze combined with bilayer multi-channel which equips with stratified lines and tick marks. This device is a rectangular structure composed of one square bottom and four rectangular side walls, and the channels of every side wall are composed of one upper channel and two lower channels. The center of the upper channels is in the vertical center line of every side wall, and the two uper channels of adjacent side walls are at 90° degrees with each other, and the two lower channels of adjacent side walls are at 45° degrees with each other. There are stratified lines and tick marks on the side wall to test the spatial location and movement trajectories of aquatic animals. The carp robot was put into the water maze for the underwater experimental detection. The success rates of left and right steering at 135, 90 and 45 degrees as well as forward motion of the carp robots (n = 10) were over 60%. This study showed that the device could be used to observe and test the motion of the carp robot.
ObjectiveTo systematically review the response of Kawasaki disease (KD) after an initial standard dose of intravenous immunoglobulin (IVIG) therapy and routine laboratory indexes.MethodsWe searched PubMed, EMbase, The Cochrane Library, CBM, CNKI, VIP and WanFang Data databases to collect case-control studies about the correlation between response of KD after an initial standard dose of IVIG therapy and routine laboratory indexes till 31st December 2017. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. A meta-analysis was performed by using RevMan 5.3 software.ResultsThirty studies were included. The results of meta-analysis demonstrated that the levels of hemoglobin (Hb) (SMD=–0.21, 95%CI –0.32 to –0.09, P<0.001), serum albumin (ALB) (SMD=–0.68, 95%CI –0.90 to –0.47,P<0.001) and serum sodium (SMD=–0.64, 95%CI –1.01 to –0.27,P<0.001) in IVIG non-responsiveness group were significantly lower than those in IVIG responsiveness group. The levels of alanine aminotransferase (ALT) (SMD=0.74, 95%CI 0.36 to 1.13,P<0.001), aspartate aminotransferase (AST) (SMD=0.61, 95%CI 0.24 to 0.99,P=0.001) and C-reactive protein (CRP) (SMD=0.63, 95%CI 0.38 to 0.87, P<0.001) in IVIG non-responsiveness group were higher than those in the IVIG responsiveness group.ConclusionThe current evidence shows that low levels of Hb, ALB and serum sodium and high levels of CRP, ALT, and AST are risk factors of IVIG non- responsiveness in KD. Due to limited quality and quantity of included studies, more high-quality studies are needed to verify the conclusion.
